T'O .ALL WHOM IT MAY GONCERN;

Be it known that I, WILLIAM Semoun, of Lynn, in the county of Essex, andState oi"y Massachusetts, have invented a new kand improvedWater-Closet; andI do hereby 'dclare that the following is a. full,clear, and exact description thereof, whichl-willenableothers skilled intheart to make and use the same, reference being had to the accompanyingdrawings, forming'part of this specification.

This invention` relates to a new and improved method of constructingwater-closets, whereby the same are rendered more simple in theirconstruction, and the escape of ofensivo gases from'them is prevented.In the accompanying plate of 'drawings- Figure 1 represents a centralvertical section of my invention, taken in the line :c se, g. 2.

Figure 2 represents a central vertical section of the same, taken in theline y y, iig. 1.

Similarletters of' reference indicate corresponding parts. i Y Y A is abox. or casing, in which the cover and thc' mechanism for operating thesame are cohtained; B is the movable seat, secured to the casing A bythehinges d; C is the opening in 'the seat B; D is the concave cover; Y

E is the lever, havng'upon the same the projection a2, and turns uponthe pivot e; al is a rock-shaft, to which the concave -cover isattached, having upon 'one end of--said rock-shai`t the oranti, a; e isa connecting-link, connectingthe crank, a, to the'lever E; G is aspring, held in position by a. screw,f; h is 'a casing, to protect thelever E-and the spring G.

The casing A is made in the same general form as thc casings of.water-closets now commonly in use,'and is connected with any vault orsewer in the ordinary way. l

Upon the top and front side of the casing'A is hinged a seat, B. VTheseat B is ofthe ordinary form of seats Vfor such purposes, and isprovided with an opening, C, through thesame; The coverD isa concavemetallic disk, of greater diameter than the diameter of the opening C,and is secured byV e suitable arm to an A iron. rock-shaft, al, nearthemiddlepf the same, i The object of the cover D being made concave,is, that the same may iit more tightly againstthe s eat B under theopening C, and thus more effcctually prevent the escape of gases throughsaid opening C. l v i The rock-shaft al rocks in suitable bearingsuponthe under side of the casing A, at one side of the nseat B, and extendsfrom the front to the rear ofthe same, at right angles to front of saidcasing, and is provided upon the' back endof the some with a suitablecrank, a, keyed thereto in the ordinary way, in a line parallel with thearm to which 4the concave cover D is attached. The seat B is supportedat the back edge of the same by an. upward projection, a2, upon thelever The leverV E is made of wood or other suitable material, and ifpvoted within the casing A at one end, to the back of said casing A, onthe side of the same opposite. to the rock-shaft al, as shown in thedrawing, iig. l. The lever E is supported at the other end in nearly nhorizontal position, by a metal licV spring, G, properly secured to andwithin the casing A under the lever E, by the screw f, as shown. l I

The lever E is connected with the crank al, by a metallicconnecting-link, e, as shown, so that the'force 'of the spring Gr will4hold the concave cover D firmly against the under side of the seat B,at the same time supporting the seat B by means of the projection-a2,and in such way as that by any pressure upon the seat B, as the weightof any occupant of the same, thc lever E will be forced down, and theconcave cover connected thereto, as above shown,.will be carrieddownwards and sdewise, and so to be entirely out ofthe way.

In the casingA is a pipe, F, made of wood or tin,`or other suitablematerial of suilicient size to carry off vany gases which may arise,and'would otherwise be contained in said casing, said pipe F openingat'the other end into any due or chimney. y

I claim as new, and desire to secure by Letters Patentp In combinationwith the casing A, having outlet F and hinged seat B, the concave coverD, rock-shaft al, link e, pivoted lever E, having extension a2, andspring G, all constructed and arranged to operate in the manner and for`the purpose/'substantially as herein shown and described.
